Mesh Methods

      Hello dear members


       


      I get confused about selection mesh methods. Especially between tethrahedral and hex dominant.


      What is the way of thinking on choosing them?


      When should I use tetrahedral?


      Can we make an interpretation?


       


      Thanks

      10 node tetrahedrals are good elements (not 4 nodes) - of course you need more tets than hexahedral to cover the same volume (say a cube), so you do get more elements with tets. On the other hand it is not possible to mesh any/all geometries just with only hexahedrals, but if you can then use them.
